摘要
通过对杉木不同密度的毛竹杉木混交林的生产力、林分生物量、土壤肥力、水文学特性、经济效益等调查分析 ,应用大系统多目标层次分析法对各种模式进行定量评价 ,找出经济与生态效益最协调的混交模式为杉木密度 1 80 0株 /hm2 的毛竹杉木混交林 ,其次是毛竹纯林 ,第 3是杉木密度 1 350株 /hm2 的混交林 ,第 4是杉木密度 90 0株 /hm2 的混交林 ,第 5是杉木密度450株 /hm2的混交林 。
Based on the data of productivity, biomass, soil fertility, hydrology feature and economic profits collected from mixed forests of Chinese fir and Phyllostachys heterocycla cv pubescens in different density stands, the comprehensive \{effects\} of different pattern are evaluated by applying the method of AHP The results show that the total permutation of comprehensive effects are in the following sequence: the mixed forest with 1 800 per hectare of Chinese fir>pure forest of Phyllostachys heterocycla cv pubescens>mixed forest with 1 350 per hectare of Chinese fir>mixed forest with 900 per hectare of Chinese fir >mixed forest with 450 per hectare of Chinese fir>pure forest of Chinese fir
